How many are interested in a thread on this subject? We have a TroyBilt Pony about 30 yrs. old. The carbarator is the problem with it too. Since that engine is no longer made getting a new carborator isn't possible. Tried it already. Now I have a Mantis. I absolutely love it. It will do anything the Troybilt will/can do and is easier on me as well. I tear up praire sod that is heavy with old time fescue, etc. all the time. I don't know what I would do without it. DH bought me one of those hoe type things once. I told him I need a tool not a toy and took it back.
